# rMosaicSet

##### Mosaic Random Set

Generate a random set by taking a random selection of tiles of a given tessellation.

##### Usage

`rMosaicSet(X, p=0.5)`

##### Arguments

- X
- A tessellation (object of class
`"tess"`

). - p
- Probability of including a given tile. A number strictly between 0 and 1.

##### Details

Given a tessellation `X`

, this function
randomly selects some of the tiles of `X`

,
including each tile with probability $p$ independently of
the other tiles. The selected tiles are then combined to form a
set in the plane.

One application of this is Switzer's (1965) example of a random set
which has a Markov property. It is constructed by generating `X`

according to a Poisson line tessellation (see `rpoislinetess`

).

##### Value

- A window (object of class
`"owin"`

).
